Birmingham: Alastair Cook's side hold a 2-0 lead in the five-match series, with a comfortable six-wicket win at The Oval last Sunday making it very tough for the touring Australians to come out of the series with anything.
England can overtake their opponents at the top of the one-day international rankings with a clean sweep of the series but Bailey says that is unlikely and believes his side can still win the series.
For Australia, Bailey made a patient 65 from 86 deliveries in Sunday's match, but took a long time to get going, robbing Australia of momentum through the middle part of their innings.
They finished with a score of 7-251 – which proved to be well below-par – and although Bailey ended his innings with a flurry of boundaries, he ultimately lost his wicket at a crucial period.
The Tasmanian believes it is a confidence issue and knows he needs to start more aggressively in Wednesday's match at Edgbaston.
England all-rounder Chris Woakes was drafted into the squad as a replacement for Jade Dernbach and with Jimmy Anderson still recovering from a groin injury, could feature in Birmingham.
Stuart Meaker and Jade Dernbach were scheduled to miss out on this particular match as they were to attend the funeral of their county team-mate,
